High-Precision Dove Prism for Image Rotation - China Suppliers & Factory Offering Custom Optical Solutions

Core Functions

• Image Rotation & Inversion: Rotates image by 180° for collimated beams; prism rotation θ induces image rotation 2θ, ideal for optical alignment and orientation correction.
• Total Internal Reflection: Operates via critical angle principle—requires clean surfaces and collimated light for optimal performance.

Technical Specifications

• Materials:
  • H-K9L Glass: High transmission in visible range, cost-effective;
  • UV Fused Silica: Broadband UV-NIR (185nm–2.1μm), low thermal expansion.
• Precision: Surface flatness λ/5 (@632.8nm), clear aperture >90%; Diameter tolerance 0/-0.1mm, bevel 0.2±45°, scratch/dig 40/20.
• Coatings:
  • Anti-Reflective (AR): Single/dual-sided for specific wavelengths;
  • Broadband AR (BBAR): UV-NIR coverage, transmission >99% (customizable).

Applications

• Optical Imaging: Image orientation correction in microscopes and endoscopes.
• Laser Processing: Beam rotation and path adjustment for multi-axis systems.
• Astronomical Instruments: Field rotation compensation in telescope imaging.

Customization

• Tailored dimensions, specialized coatings (e.g., water-resistant GT-7 lacquer), and bulk orders.
• ISO 10110 compliant drawings and test reports for traceable optical performance.

Ultra-High Precision

Optional λ/10 surface flatness for interferometers and high-sensitivity systems.

Environmental Robustness

Hard coatings or sealed lacquers enhance moisture/dust resistance for industrial harsh conditions.
